VMware How To: Create a NFS Shared Transfer Area

When setting up a multi-cell vCloud Director environment you will need to create a shared area to store the transfer folder that is used whenever something is uploaded to a vCloud Director cell, such as an ISO or an OVF template.

The diagram below shows a typical multi-cell, multi-vCenter setup.

In order to create the share we can use a CentOS virtual machine as the shared area. Any NFS mount will suffice provided that it allows for ownership of folders to be set. This guide will assume you have already created the NFS share.

This guide also assumes this is being run on a new vCD cell. If you have already deployed vCloud Director take a backup of the contents of the /opt/vmware/vcloud-director/data/transfer folder before you start otherwise any uploaded content that hasn’t yet been copied to a datastore will be lost.
Also if the cell already exists you can skip step 1. Just make sure to stop the cell service first.service vmware-vcd stop

VMware How To: Create A Custom ESXi Bootable ISO With Third Party Drivers

If you have wondered how you can go about creating your own ESXi image complete with any drivers, such as storage controller drivers or network card drivers then you can use PowerCLI imagebuilder to achieve this.
This is helpful if the standard ESXi image is causing a purple screen of death (PSOD) when trying to boot up ESXi.

To do this you will need a copy of PowerCLI, you can download the v5.5 from the VMware website.
Once installed, set the execution policy to remote signed.
